"I play very sweet characters, so people look at me like I'm the kid from The Wonder Years, rather than Brad Pitt."

Last year, O'Dowd tried to break away from 'nice-guy' roles and filmed sex scenes in the TV adaptation of The Crimson Petal And The White for the BBC.

The 32-year-old said that he wants a second chance to portray such scenes after experiencing unfavourable filming conditions the first time around.

"It was weird because the first time I was naked, I had to get out of a coldish bath, and I was like, 'Oh, great'," he explained.

"I'd do it again. Please give me the opportunity!"

O'Dowd also joked that a sex tape featuring him and his new wife won't be making its way online anytime soon.

"Well, so many of my sex tapes are already online that I feel I don't want to saturate it," he quipped. "Though you're only as good as your last job - if I put in a great performance sexually, it would do nothing but advance my career."
